Preventing Form Submission on Remove Button Click
In the provided HTML form, the "remove" button triggers form submission when clicked. To prevent this behavior, it's essential to understand that the HTML5 button element has a default behavior of submitting the form, as defined by the W3C specification.
To override this default behavior, explicitly specify the button's type as a button:
<button type="button">Remove Last Item</button>
By setting the type attribute to "button," you instruct the browser to treat the button element as a button that initiates custom JavaScript code (in this case, the removeItem() function) instead of submitting the form.
<script>
function removeItem() {
// Custom code to remove the last row
}
</script>
This modification ensures that the "remove" button will no longer submit the form when clicked, allowing you to perform other actions, such as removing a row from a table or updating data in an application, without triggering form submission.
The above is the detailed content of How Can I Prevent a Button from Submitting an HTML Form?. For more information, please follow other related articles on the PHP Chinese website!

In JavaScript, choosing a single-line comment (//) or a multi-line comment (//) depends on the purpose and project requirements of the comment: 1. Use single-line comments for quick and inline interpretation; 2. Use multi-line comments for detailed documentation; 3. Maintain the consistency of the comment style; 4. Avoid over-annotation; 5.
